OIL-BURNER.

SPECIFICATION forming part of 'Letters Patet No. 772,496, dated october1s, 1904. Application iled May 23, 1904. Serial No. 209,329. (No model.)

To a/ZZ whom, it may concern:

Be it known that I, J oIIN BRENING, J r.,`a citizen of the UnitedStates, residing at Mc- Cook, in the county of Redwillovv and yState ofNebraskahave invented certain new and useful Improvements inOil-Burners; and I do declare the following to be a full,'cle'ar, andexact description of the invention, such as will enable others skilledin the art to which it appertains to make and use the same.-

This invention relates to oil-burners ofV that type specially adaptedfor use in connection' v with steam-boilers and in which the fuel-oilemployed is vapor-ized and injected with steam into the lire-box of thefurnace and there consumed to generate steam.

The object of the invention is to provide a burner of thischaracter-which is efficient for use on steam-boilers of different typesand which embodies certainl improved features of construction andcombinations of parts, as

` hereinafter described and claimed.

In the accompanying drawings, Figure 1is a sectional view through aportion of a boiler equipped with my invention. Fig. 2 is a sectionalview through the burner `on an enlarged scale, and Figs. 3, 4, and 5 aresimilar views of interchangeable injector nozzlesv adapting the devicefor use in connection with different types of boilers.

Referring now more particularly to the at a point between its ends andreceiving the threaded end ofv an oil-supply pipe 7, leading from thetank 3, said pipe being provided with a controlling-valve 8', wherebythe How of oil to the burner may be regulated.

Extending longitudinally Within land through the tubular body or casing5 is a steam-nozzle 9, which is provided at one end with a taperingpoint 10 to eject the steam in a jet to commingle with the oil and sprayit into the fire-box 1. The opposite end of the nozzle 9 is externallyscrew-threaded,as shown at 11, for connection with a coupling 12,connecting the same with one end of a steamsupply pipe 13, leading fromthe steam-dome 2 of the boiler.

The outer end of the body or casing 5 of threads 14 for connection witha coupling 15, which has a threaded portion 16 to engage the threads 14,an outer sleeve 17, and an intermediate polygonal portion 18, the latterprojecting beyond 4said sleeve and adapted for Vthe application of awrench, by means of which the coupling may be conveniently connected toand disconnected from the body or casing 5. The inner face of thepolygonal vportion may be provided with a suitable wheel or othersuitable form of grip 24, as

will be readily understood. Themovement of this hand-wheel in onedirection or the other will adjust the nozzle 9 longitudinally toregulate the jet action of the tip 10.

The inner end of the tubular body or casing 5 is provided with internalscrew-threads 26 to receive a coupling upon the end of an injectornozzleof suitable construction. In the drawings I have shown three differentforms of interchangeable nozzles which adapt the device for use upondifferent types of boilers and boilers of different capacities. Thenozzle 26 (shown in Figs. 1, 2, and 3) is ,designed for small boilersand ordinary stationary boilers and comprises a tapering body portion27, having at its inner end a screw-threaded coupling' 28 to engage thesaid threads 25 and provided at a` point in advance of said couplingwith a polygonalportion 29 to adapt it to be conveniently applied andremoved. In the construction shown in Fig. 5 the nozzle 26' is theburner is provided with internal screw- IOO detachably fitted upon theend otl an independent coupling-pipe 30, which is provided with athreaded end 28 and polygonal portion 29, similar to the correspondingpart-s o'tl the nozzle 26. The detachable connection in this case ismade by forming the nozzle with a cylindrical end 31, fitting upon areduced portion 32 of the coupling and secured thereto by screws or likefastening devices 33; but any other desired form of connection may beemployed. rlhe nozzle 26' further differs from the nozzle 26 in form andsize, being made of truste-conical shape or bell shape to project thehydrocarbon vapor and iiames over a greater area in the tire-box of theboiler. This type ot' nozzle is especially adapted for use in connectionwith boilers having ordinary straight lines. The nozzle 26 and couplingshown in Fig. correspond to those shown in Fig. 4, except that thenozzle is disk-shaped and has a greater ilare to project the vapor andflames over a still wider area. This construction is employed when theburner is applied to boilers of the return-Hue type, thus preventing aback action of the products of combustion.

In the operation of the device the controlling-valves in the oil andsteam pipes are opened, and the oil flows through the pipes 7 into thecasing 5 and is drawn upward into the injector-nozzle by the suctionproduced by the steam escaping from the tip 10 ot' the steam-nozzle 9,the jet ot' steam escaping from the tip lO further causing the oil to beprojected into the lire-box l in the form of spray, which being therebycommingled with the steam is placed in condition for completecombustion. By adjusting' the hand-wheel the steam-nozzle 9 may be movedlongitudinally to set the tip l() at different points with relation tothe nozzle 26, thus regulating the effect of the blast and the suctionaction of the oil.

From the foregoing description, taken in connection with theaccompanying drawings` the construction and operation oi the inventionwill be readily understood without re quil-ing a more extendedexplanation.

Various changes in the torm, proportion,

and the minor details ot construction may be L resorted to withoutdeparting trom the principle or sacrilieing any oi the :ulvantages oithis invention.

Having thus described my invention, what l claim, and desire to secureby Letters latent, isw

l. In an oil-burner, the combination with a casing provided at one endwith a discharge,- nozzle, ot' a source ot' oil-supply communicatingwith the easing, an adjustable steam-injector disposed within the easingand having a threaded surface, means tor supplying steam thereto, acoupling upon the end ot the casing opposite the nozzle, ay nut engagingthe steam-nozzle, and adjusting means conneetml to the nut and revolnblyconnected with the coupling, substantially as described.

2. In an oil-lnirner, the combination with a casing provided at one endwith a d isehargenozzle, of a source of oil-supply communieating' withthe lasing, a steam-injector having a nozzle and disposed within thecasing, said injector having a threaded surface, a sleeve on the casing,a hand-nut having a tubular portion entering the sleeve, a couplingconnccted to the sleeve and to the casing, and means whereby saidhand-nut may be rotated independently ot the coupling to adjust theinjector relatively to the discharge-nozzle ot the casing, substantiallyas described.

In testimony whereof l have hereunto set my hand in presence ot' twosubscribing wit` nesses.
